r This invention relates to inflating devices and more particularly toglove inflaters for distending the body and fingers of a glove after thesame has been cleaned to permit the glove to dry in distended position.

The principal objects of the invention are to provide convenient meansfor controlling into a glove mounted on an inflater for reducing thelabor scribed.

and time necessary to properly shape the Other objects of the inventionwill be apparent in the course of the following description of one formota glove inflater embodying the invention and illustrated in theaccompanying drawing, wherein:

Fig. 1 is a perspective view of a glove intlater constructed inaccordance with the invention, an air supply pipe and operating pedalbeing shown fragmentarily.

i Fig. 2 is a longitudinal vertical section through the device on theline 2-2, Fig. 3.

Fig. 3 is a section on the line 33, Fig. 2.

Referring in detail to the drawing:

l designates a hollow tubular casing or nozzle member considerablyelongated to provide relatively extensive inlet and outlet portions 6and 8 having chambers 10 and 12 of substantial volume and communicatingthrough a valved port as later de- Fhe outlet end is flattened and hassubstantial width and is formed to fit snugly within the wrist of aglove as shown in Fig.

1. The nozzle is preferably elongated in cross section and is thusadapted to fit the wrist of a glove. 1

A reduced n'pple portion 14 on the inlet end of the nozzle is connectedto a line 16 leading from a compressor or other means for supplying airunder pressure (not shown), whereby the inlet chamber 10 of the nozzleis in constant communication with the source of supply, and air isalways present under pressure in said chamber.

The inlet portion of the nozzle member is provided with lateral bracketwin s 18 having apertures to receive bolts for ring the device to thetop of a table so that the outlet end may project from the edge of thetable.

Formed in the middle portion 01"" the nozzle in front of the wings 18 isa valve body element including a partition 20 having a horizontal wallportion 22 slightly above the horizontal middle plane of the nozzlechannel and provided with a port 23 forming a beveled seat for a valve24 operating below the wall 22. v i

The valve includes a spiderdike upper guide portion 25 for centering thevalve on the port, and an integral stem 26 projecting into a recess 28formed in a plug 30 threaded into an opening 32 in the lower wall ofthe. nozzle. A coil spring yieldingly holds the valve against the portseat.

A valve-operating rod or stem 36 movable in an opening 38 in the upperwall of the nozzle bears against the valve spider and is guided in anelongated externally threaded sleeve lO threadedly mounted in theopening 38. The sleeve afiords means for mounting stem packing and stemoperating elements on the nozzle as presently described.

Threaded on the sleeve is anut 42 seated on a boss at formed on theupper side of the nozzle, and the apertured horizontal arm 16 of" a yoke48 is freely movable over the sleeve to rest on the nut and providedwith ears 50 at the upper end of the vertical portion of the yoke,apertured to support a pivot pin 52 and spaced to accommodate theenlarged end 54 of a lever 56 mounted on the pin. A nut 58 is threadedon the sleeve to retain the yoke on the nozzle, and a guide cap or gland6O threaded on the top of the sleeve retains packing 62 in engagementwith the stem.

The lever extends transversely of the noz zle over the path of the stem36 and when depressed will engage the stem to urge the same against thevalve. A link 64: pivoted in the outer end of the lever is pivotallyconnected to a pedal lever 66 having a mounting on the floor beneath thenozzle.

Depression of the pedal will depress the lever against the stem and movethe stem and valve against the influence of the spring to permit airunder pressure in the nozzle and supplied from a source not shown, topass through the partition port into the outlet end of the nozzle.

PATENTOFFICE When the pedal is released, the spring 34: will move thevalve to close the port, and incidentally push the stem 36 against thelever 56 to elevate the same and retract the pedal.

In order to limit upward pivotal movement of the lever 56, a dependingtongue 68 is formed on the end 5% of the lever and swings intoengagement with the edge of the wall portion 70 of the yoke at thebottom of the spacing slot between the ears 50, when the lever has beenretracted suii'iciently to permit the valve to close the port.

In using the device, a glove may be mounted on the outlet end of thenozzle and retained by hand while the operator presses the pedal toadmitair into the chamber 12 to pass into the glove for distending the glove.7

When the pedal is released the spring in the nozzle will move the valveto close the port. A substantial amount of air will be retained in thenozzle portions to prevent sudden and complete exhaustion of airpressure and thus tend to maintain necessary pressure to remove thewrinkles from the glove to restore its shape and size.

A substantial volume of air will be retained. under pressure in thelarge chamber 10, and air under pressure may move rapidly through therelatively large port when the valve is opened into the outlet chamber.The air in the outlet chamber is thus quickly put under pressure, andthe outlet chamber is sufiiciently long and has suiiicient crosssectional area to prevent rush of thin jets of air into the glove.

The inlet chamber 10 may be of any desired shape, but in any event willhave substantially greater volume than an equal length of the supplypipe. The outlet chamber preferably hassubstantially the same volume asthe inlet chamber.

lVhat We claim and. desire to secure by Letters Patent is:

A glove infiater including a nozzle having an open end rectangular incross section and curved at its edges to receive and shape the wristportion of a glove thereover and support the glove thereon, a partitionin said nozzle forming inner and outer chambers therein and providedwith a valve port, an air supply line connected with the inner chamber,a valve spring-pressed to close said port in the direction of flow ofair through the nozzle, a thrust rod. engageable with the valve,

a yoke mounted on the nozzle, and a lever on the yoke engageable withthe thrust rod to open the valve.

In testimony whereof we afliX our signatures.
